In building design, there is an ongoing trend of research focused on various techniques for decreasing energy consumption in buildings, which can reduce the effect of global warming. This work is inspired by the passive heating system “Trombe Wall” which consists generally of a masonry unit located at the façades, covered with a glass layer, and collects heat energy from the sun due to a black coating at the exterior side of the wall. However, it has some drawbacks: e.g., Trombe Wall is static, heavy, hard to integrate into contemporary architectural facades. To solve these problems, a dynamic Trombe Wall system called “Heat Pocket” has been designed. Heat Pocket consists of aluminum panels that are filled with phase change material (PCM), their exterior facing surface is painted with a selective black coating which converts solar energy to heat, and this thermal energy is stored in the PCM. In this work, the proposed system was simulated to assess if the system would satisfy ASHRAE thermal comfort levels during the day for the virtual room having an interior space of 7.3 m x 5.4 m x 3.5 m; in cold climate conditions of Van, Turkey; in the month of December. Findings show for the 100% PCM-filled panel, Heat Pocket is able to increase and retain the indoor by a minimum of 18.5 °C compared to outdoor temperatures. The system was able to satisfy ASHRAE thermal comfort levels completely throughout the analysis time, after the first 3.3 meters away from the glass façade.

CHARACTERIZATION OF LATENT THERMAL ENERGY IN A STORAGE UNIT WITH FIBONACCI-SEQUENCE-INSPIRED FINS Baghaei Oskouei, Seyedmohsen; Bayer, Özgür; Department of Mechanical Engineering (2023-1-19) Latent thermal energy storage (LTES) is a viable method to mitigate one of the main problems with renewable energy sources, such as solar energy, which is their intermittent nature. LTES units take advantage of the large latent heat of fusion in phase change materials (PCMs) to store a substantial amount of energy in a relatively small volume, making them efficient and economical. The major challenge with PCMs is their low thermal conductivity, eventuating long melting (charging) and solidification (dischar...
A data-driven approach for predicting solar energy potential of buildings in urban fabric Duran, Ayça; Gürsel Dino, İpek; Department of Architecture (2022-7) Energy-efficient buildings that use clean and sustainable energy sources are urgently needed to reduce the environmental impact of buildings and mitigate climate change in cities. Buildings have great potential in harvesting solar energy by their solar exposure capacity. Developments in PV technologies also encourage the integration of PV systems into architectural applications. However, urban contexts can limit solar energy generation capacity of buildings by shading building envelopes and reducing availab...
Development of silica fume-based geopolymer foams Shakouri, Sahra; Bayer, Özgür; Erdoğan, Sinan Turhan (Elsevier BV, 2020-11-01) Thermal insulation materials are critical for reducing the energy consumption and carbon emissions associated with buildings. A good insulation material must not only have low density and sufficient mechanical properties but also resist high temperatures and fires. In addition, its production process must be simple and inexpensive. This study describes the production of very low density (>85 kg/m(3)) inorganic foams with high porosity (<94%). Silica fume and NaOH solutions are mixed to prepare a geopolymer ...
DEVELOPMENT OF THE FUNCTIONAL POLYMER COATINGS BY USING A GREEN APPROACH TO MODIFY PROPERTIES OF DIFFERENT SURFACES Tuna, Melek; Önal, Ahmet Muhtar; Mustafa, Karaman; Department of Polymer Science and Technology (2022-1) Significant activities have been carried out by the global research community to develop alternative sustainable building materials and energy efficient production methods, that result in more economical and sustainable building material production adhering to the comfort and aesthetic standards needed today. With the improvement of material science, polymer materials display application possibilities credited to their excellent properties compared with the inorganic materials, such as antibacterial, non-f...
Effect of bypassing the heat transfer fluid on charging in a latent thermal energy storage unit Baghaei Oskouei, Seyedmohsen; Bayer, Özgür (2023-06-01) Horizontal latent thermal energy storage (LTES) systems that use phase change materials (PCMs) are popular and effective methods of alleviating the intermittency of renewable energy sources. The main issue of PCMs is their low thermal conductivity, resulting in long charging times and slow response. In this investigation, a novel method to overcome this issue is proposed by designing bypassing tubes that redirect the flow of heat transfer fluid to the bottom of the horizontal LTES tank, where the melting ra...
